and this application October 19,1938, Serial No. 235,730 r 9 Claims. (01. 205-25) This-invention relates to wire drawing mechanism and more particularly to. an arrangement and mounting of dies for a mechanism of this type.

One of the objects of the invention is to provide a wire drawing mechanism in which the die or dies may shift to take a position determined by the position of the wire. Preferably the die is shiftably supported on a flat surface a die holder so that it may be moved by the wire to such a position that the wire will pass straight through it.

Another object of the invention is to provide a wire drawing mechanism, in which the die maybe adjusted to aline its opening with the wire. According to one feature of the invention this adiustment may be performed by providing adlusting screws on the die block engaging the die holder to change the angle of the die without interfering with its shifting.

Still another object of the invention is to provide a wire drawing mechanism in which a lubrieating device for lubricating the wire is carried by and shiitable with the die. In one desirable arrangement the lubricating device comprises a lubricant container detachably carried by the die block and divided by a partition into a large container and a small container through which the wire passes. In this way deteriorated lubricant may be removed from the small container without containing lubricant in the large container.

The above and other objects, advantages, and novel features of the invention will be apparent from the following description when read in connection with the accompanying drawing, in which:

Figure 1 is a partial section of a wire drawing mechanism illustrating the die mounting; and

Figure 2 is a section through the die block substantially on the line 2-4 of Figure 1.

As shown, a die holder III is secured to the frame or the like of a wire drawing machine and is formed with a substantially horizontal portion I: having a hole I 4 therein through which the wire ll may pass.

A die block I. is loosely mounted in the die holder, resting on the horizontal portion l2, and carries a die 2| which is held in place by a sleeve 22 threaded into the die block. The die block and die may shift laterally on the portion I: so that the die' can take a position in line with the wire.

In order to adjust the die block to aline the die opening with the wire in the event it is not bored exactly pe p ndicular with it face, three vertically disposed set screws 24, are provided in the die block in spaced positions adjacent its periphery on which the die block rests on the portion II. By adjusting'these screws the angle of the die block may be changed to aline the die opening with th wire.

The die and die block are preferably cooled by forming in the die block passages 26 extending substantially around the die and connected to pipes 28. Water or other suitable cooling fluid is circulated through the pipes 28 and the passage 26 to cool the die blockand the die and it will be noted that a closed system is maintained at all times, even when a die is being replaced.

In order to lubricate the die a container for lubricatingsoap or the like is formed with a neck 30 to fit over the sleeve 22. The container is formed with a large bin 82 for soap at one side of th wire and a smaller bin or container 34 through which the wire passes. A partition 36 separates the two bins and is spaced from the bottom of the container so that soap may flow from the bin 32 under the partition into the bin 34 from whence it is fed by gravity and by the drawing action of the wire into th die. This construction permits deteriorated soap to be removed from the container 34 and prevents the supply in bin 32 from being contaminated thereby. A slide 38 is provided to close the bottom of the container so that it may be removed withv out spilling the soap when the, operator is ad- 4 been shown and described in detail it will bevunr justing or replacing the die.

In use the wire is drawn vertically downward through the die by a capstan, not shown, and is guided into the die by a guide wheel, not shown. The die may shift laterally on the die holder under the pull of the wire to a position in line with the peripheries of the guide wheel and capstan and its angle may be adjusted by the screws 24 to aline the die opening with the wire.

This application is a division of my copending application Serial No. 68,856, filed March 14, 1936.

While one embodiment of the invention, has

derstood that many changes ,might be made therein and it is not intended to limit the scope of the invention to the exact form shown not otherwise than by the terms of the appended claims.

What is claimed is: 1. Wire drawing mechanism comprising a die holder, a die block carrying a die through which holder, a die block carrying a the die opening with the wire without interfering with its shifting.

2. Wire drawing mechanism comprising a die holder, a die block carrying a die through which the wire passes and which freely shiftably engages said holder so that it may adjust its position laterally bodily to center the die opening with the wire, and a lubricant feeding lubricating the wire and which engages and shifts with the die block.

3. Wire drawing mechanism comprising a die die through which the wire passes and which shiftably engages said holder soathat it may adjust its position to that of the wire, and a lubricant feeding device for lubricating the wire and which engages and shifts with the die block, said lubricant feeding device including a large container for dry powdered soap or similar lubricant and a smaller lubricant container through which the wire passes and which two containers are separated by a partition beneath which the lubricant must pass from the large container into the smaller container.

4. Wire drawing mechanism comprising a die holder having a substantially horizontal supporting surface having an opening therein through which the wire may pass, a die block carrying a die through which the wire passes vertically downward, said die block resting loosely device for on said horizontal surface whereby it may shift laterally to the wire to center the die opening with the wire, and lubricant-feeding means mounted on and shifting with said die block.

5. Wire drawing mechanism comprising a die holder having a substantially horizontal supporting surface having an opening therein through which thewire may pass, a die block carrying a die through which the wire passes vertically downward, said die block resting loosely on said horizontal surface whereby it may shift laterally of the wire to center the die opening with the wire, and means for adjusting the plane of the die block to aline the die opening with the wire.

6. Wire drawing mechanism comprising a die holder having a substantially horizontal supporting surface having an opening therein through which the wire may pass. a die block carrying a die through whichthewire passes vertically downward, said die block resting loosely on said horizontal surface whereby with the wire, and adjusting screws carried by the die block and engaging the supporting surholder having a substantially horizontal supporting surface having an opening therein through which the wire may pass, a die block carrying a die through which the wire passes vertically downward, said die block resting loosely on said horizontal surface whereby it may shift horizontally in any direction laterally of the wire to center the die opening with the wire, and a lubricant feeding device for lubricating the wire and which is carried by and shifts with the die block.

8. Wire drawing mechanism comprising a die holder having a substantially horizontal supporting surface having an opening therein through which the wire may pass, a die block carrying a die through which the wire passes vertically downward, said die block resting loosely on said horizontal surface whereby it,may shift to adjust its positionto that of thewire, and a lubricant container carried by the die block around the die having a partition spaced from its bottom and dividing it into a large container and a smaller container through which the wire die block.
